twisted light News
Researchers Structure Light with Two Independent Orbital Angular Momenta
LOS ANGELES, Aug. 26, 2020 — Researchers at the University of Southern California (USC) combined twisted light and optical frequency combs to produce a new, dynamic light structure. The Optical Communications Lab at USC had been researching twisted light beams and frequency...
Photonic Crystal Generates VUV Light at Wavelengths Suitable for Spectroscopy
TOKYO, July 31, 2020 — Researchers at the University of Tokyo have created a tabletop device that efficiently generates circularly polarized vacuum ultraviolet (VUV) light using an ultrathin film with nanoscale perforations. VUV wavelengths, which can be absorbed by air...
Multidimensional Quantum Communications with Legacy Fibers
JOHANNESBURG, Jan. 28, 2020 — In a new “twist” on quantum communication using optical fiber, researchers from the University of Witwatersrand (Wits) and Huazhong University of Science and Technology (HUST) have demonstrated that multiple quantum patterns of twisted...
Microgears Made from Germanium Generate Twisted Light
SOUTHAMPTON, England, Dec. 31, 2018 — Miniature gears made from germanium have demonstrated the ability to generate light that has orbital angular momentum. This new light source could be used to boost the amount of data that can be transmitted through optical computing. Light carries...
Vortex Laser May Help Shape the Future of Data Transfer
BUFFALO, N.Y., Sept. 6, 2016 — A light-based communications tool that is structured to carry data in a helical path may enable fast transfer of large amounts of data, resolving potential bottlenecks in data transfer as the demand for information sharing grows. The novel technique...
Twisted Light Characterization Technique Seeks to Advance Quantum Communications
ROCHESTER, N.Y., April 16, 2016 — Fully understanding “twisted” light may enable its use in quantum communication applications, and an experimental technique has yielded the first characterization of the azimuthal Wigner distribution of a photon. Twisted light has raised...
Shifting Modes Enable Free-Space Optical Communication
VIENNA, Nov. 12, 2014 — Twisted beams of light have been used to transmit images through the air over 3 km, demonstrating significant data-carrying capacity of light in free-space communications. A team from the Institute for Quantum Optics and Quantum Information (IQOQI),...
Terabits transmitted by twisted light
LOS ANGELES – Do you ever wish you could download that Netflix movie you’ve been dying to see in a matter of just a few seconds rather than those 15 long, grueling minutes, or watch the latest viral YouTube video without the hassle of buffering? Well, your...
Twisting Light Sends Data Speeds Soaring
LOS ANGELES, June 26, 2012 — Beams of light that are twisted and combined to transmit data at dramatically increased speeds soon could lead to the fabrication of high-speed satellite communication links or be adapted for use in fiber optics.
Twisted physics
BRISTOL, UK – A group of UK scientists has light theory all tied up in a paper published in the February 2010 issue of Nature Physics. Using lasers under holographic control, Dr. Mark Dennis and fellow physicists at the universities of Bristol, Glasgow and...
